There are many ways to increase the efficiency of your air conditioner without having to call an HVAC professional. Of course, you should leave the more complicated electrical work to the pros, but there are a few things you can do on your own. Cleaning the ducts and air registers will increase the airflow and air quality of your AC. It is probably one of the easiest ways to improve your air conditioner output. This article explains how you can clean your air ducts and registers with simple and affordable tools.
Removing the Air Registers
The air registers are secured to the wall with screws that can be removed with a power drill. This will strip the paint off of the screw head, so it is a good idea to buy new screws before reattaching the registers. The register edges might also be caulked to seal them to the wall. If so, cut away this caulk with a razor blade.
Cleaning the Registers
The key to cleaning the air registers is wiping down the backside and making sure you get all of the dust out of each individual vent. You can even clean your registers in the sink with a scrub brush and mild soap.
Cleaning the Air Ducts
To properly clean the ducts, you need a telescoping pole and a duct cleaning brush attachment. Most telescoping poles have a universal attachment, but make sure your brush will screw onto it. Also, make sure your pole can extend to at least 12 feet. This will enable you to clean most duct systems.
The key to using the pole and brush attachment is to try and guide it all the way to the back of the duct without rubbing the walls too much. Then, slide the pole out of the duct, pushing down on one sidewall as you do. Repeat this step for all 4 walls of the duct.
Sweeping all this dust out of the duct can cause a big mess. One solution is to have a helper vacuum off the brush as you pull it out of the duct. This sweeping will also drag the dust in between the drywall and duct opening where there is usually a lip. Vacuum the dust out of this lip before you reattach the air registers.
As you can see, this job is not very complicated or time-consuming. It is definitely worth investing in a telescoping pole and duct brush if you want to keep your ducts clean. For more tips or to have a professional clean your ducts, talk to an HVAC company like Ron Hammes Refrigeration.
